摘要：为致力于成为未来奥运顶级赞助商的中国企业提供建设性的思考。主要采用文献资料法、专家访谈法及工作经历对奥运伙伴计划在发展过程中存在的问题进行分析,并运用经济学、市场营销学、财务管理的理论知识对奥运经济进行深入研究,以丰富和补充国内对奥运经济领域研究的不足。研究认为：当下奥运伙伴计划面临4个主要的问题：赛事赞助投资回报率直接对奥运伙伴计划产生影响。高额的赞助版权费以及长期投资收益的不确定性,影响赞助商的投资意愿。电视收视率的下降也必然会影响企业在媒体的曝光度,另外,社交媒体被大众的广泛接受这也为赞助商提供了更多的营销活动平台。国际奥委会的规则条款限制了部分顶级赞助商商业利益的最大化。 相似文献

Column Editor's Note. This column focuses on formal collaboration and networking among libraries through consortia. It offers in-depth examinations of issues facing modern library consortia including (but not limited to) e-resource licensing, ebooks, next generation integrated library systems, shared print archiving, shared digital repositories, governance and other relevant topics. Contributions are accepted for this column and must be submitted to George Machovec (george@coalliance.org). Contact the column editor for suggested topics, deadlines and formatting.
ConnectNY has been involved in consortial e-book projects since 2010. Based upon the experience of these group e-book projects, we will explore different methods for assuming the shared cost of group e-book programs and then describe ways in which DDA programs may promote a positive Return on Investment (ROI) for groups as compared to individual institutions. We will argue that while use is a factor that can be taken into account when distributing cost amongst members, a budget-based percentage approach will allow consortia to effectively initiate and manage such projects over time. 相似文献

为了满足某些图像的高效存储及快速传送的目的,提出一种基于感兴趣区域（ROI）的压缩算法。对图像进行分析,选出ROI区域,并在小波变换的基础上,对ROI小波变换低频子带采用无损编码的方法,而对ROI高频子带及非ROI小波变换子带采用改进的SPIHT压缩编码算法。在保证了图像所含信息量的同时,增加了图像的压缩编码效率。 相似文献

Increasing adoption and implementation of social media applications suggests a cultural shift in the way special collections departments communicate with external constituents. Research shows many social networking tools are used successfully to connect with special collections patrons, but limited documentation exists to describe whether special collections departments receive demonstrable returns for the time, effort, and energy expended to sustain social media activity. This article provides the results of an empirical study that examined social media usage in special collections departments at 125 Association of Research Libraries member institutions. By analyzing publicly available data from profiles on a variety of social media platforms, the authors explore how special collections units employ social networking tools and whether it is possible to determine success in terms of benefits received by the department, such as increased dialogue between departments and supporters. By using return on investment, this study found that special collections departments achieve moderate success when using social media to advertise collections, events, and activities, but they have little success when using social media to engage with external constituents. To address less successful aspects of social media projects, departments can engage in routine assessment activities, such as return on investment, to make the most of new technologies. 相似文献

Flower image retrieval is a very important step for computer-aided plant species recognition.In this paper,we propose an efficient segmentation method based on color clustering and domain knowledge to extract flower regions from flower images.For flower retrieval,we use the color histogram of a flower region to characterize the color features of flower and two shape-based features sets,Centroid-Contour Distance(CCD)and Angle Code Histogram(ACH),to characterize the shape features of a flower contour.Experimental results showed that our flower region extraction method based on color clustering and domain knowledge can produce accurate flower regions.Flower retrieval results on a database of 885 flower images collected from 14 plant species showed that our Region-of-Interest(ROD based retrieval approach using both color and shape features can perform better than a method based on the global color histogram proposed by Swain and Ballard(1991)and a method based on domain knowledge-driven segmentation and color names proposed by Das et al.(1999). 相似文献

INTRODUCTION There are about 250000 named species offlowering plants and many plant species that havenot been classified and named. Plant classificationand identification is a very old field. So far, thistime-consuming process has mainly been carriedout by taxonomists and/or botanists. A significantimprovement can be expected if the plant identifi-cation can be carried out by a computer automati-cally or semi-automatically with the aid of imageprocessing and computer vision techniqu… 相似文献
